Dynamics of quantum driven dissipative systems

Quantum systems interact with two classes of external sources. Controlled external driving fields, which allow manipulating the quantum state, and uncontrolled sources that lead to dissipation and the degradation of desired quantum features. The theoretical understanding of the interplay between the two types of external sources and their effect on the system dynamics is essential for the development of accurate control methods and the analysis of thermodynamic processes in the quantum regime. Nevertheless, due to the vast number of degrees of freedom in the environment, a general accurate dynamical description of driven dissipative systems remains beyond the current analytical and numerical capabilities. In my talk, I will describe various novel approaches to obtain a thermodynamic consistent dynamical equation of motion of dissipative driven systems, which constitutes the basis for open system control. The theory was employed to engineer control protocols for entropy-changing tasks, such as rapid equilibration and cooling. These protocols were incorporated within the operation of quantum heat engines, allowing to identify quantum thermodynamic signatures. Finally, with the aim of unifying different quantum thermodynamic paradigms, we employed an axiomatic methodology to determine the structure of the dynamical equations. This framework allowed relating various formulations of the first law of quantum thermodynamics and highlights a fundamental connection between dynamical symmetries and thermodynamics.
